Description
Hey,
I tried to implement this into a project and i have had in issue with actually getting it to give me a value of what the license plates characters are. I get this when i debug for the value of result. result={"error":true,"msg":"Error initializing Open Alpr"}. I am not sure of what the issue is. I tried using your sample project and it reached the same issue. Attached is a screenshot of the code where this issue occurs. I know that i am not missing a file where I have already tried your version and received the same problem.
The code in the photo for this method is as follows:
@OverRide
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_IMAGE && resultCode == Activity.RESULT_OK) {
final ProgressDialog progress = ProgressDialog.show(this, "Loading", "Parsing result...", true);
final String openAlprConfFile = ANDROID_DATA_DIR + File.separatorChar + "runtime_data" + File.separatorChar + "openalpr.conf";
BitmapFactory.Options options = new BitmapFactory.Options();
options.inSampleSize = 10;
// Picasso requires permission.WRITE_EXTERNAL_STORAGE
Picasso.with(MainActivity.this).load(destination).fit().centerCrop().into(imageView);
resultTextView.setText("Processing");
AsyncTask.execute(new Runnable() {
@Override
public void run() {
String result = OpenALPR.Factory.create(MainActivity.this, ANDROID_DATA_DIR).recognizeWithCountryRegionNConfig("eu", "", destination.getAbsolutePath(), openAlprConfFile, 10);
Log.d("OPEN ALPR", result);
try {
final Results results = new Gson().fromJson(result, Results.class);
runOnUiThread(new Runnable() {
@Override
public void run() {
if (results == null || results.getResults() == null || results.getResults().size() == 0) {
Toast.makeText(MainActivity.this, "It was not possible to detect the licence plate.", Toast.LENGTH_LONG).show();
resultTextView.setText("It was not possible to detect the licence plate.");
} else {
resultTextView.setText("Plate: " + results.getResults().get(0).getPlate()
// Trim confidence to two decimal places
+ " Confidence: " + String.format("%.2f", results.getResults().get(0).getConfidence()) + "%"
// Convert processing time to seconds and trim to two decimal places
+ " Processing time: " + String.format("%.2f", ((results.getProcessingTimeMs() / 1000.0) % 60)) + " seconds");
}
}
});
} catch (JsonSyntaxException exception) {
final ResultsError resultsError = new Gson().fromJson(result, ResultsError.class);
runOnUiThread(new Runnable() {
@Override
public void run() {
resultTextView.setText(resultsError.getMsg());
}
});
}
progress.dismiss();
}
});
}
}
